TO ALL WIIOM IT MAY CONCERN:

Be it known that I, F B. Mossa, of hllilwaukeain the county of Milwaukee, and State of. Wisconsin, halve invented a new and improved Means for Tighteuing Tires on Wheels; and'I do. hereby declare that the following is a full, clear, and exact description thereof, which will enab'le those Akilled in the art to make and use the same, reference being had to the accompanying drawings, forming part .f this specification, in which- Figure 1 is a side or face view of a wheel with a tire applied to it provided with my improvement.

Figure 2, a detached view ci' s portion of a tire, with its tightening parts all disconnected.

Figure 3, a detached outer or exterior viewof the ends or joint of the tire connected together.

Similar letters of reference indicate corresponding parts. l

The object of this invention is to obtain a simple means whereby tires may-be tightened on wheels at any A time when they become loose, without the aid of a smith or mechanicpand by au extremely simple and elcient arrangement of parts.

A. represents a wheel which may be constructed in the usual manner, a being the hub, b the spokes, and c the felloes thereof. B is a spcket, which may be of malleable cast iron orfotheg` suitable metal. This socket is of 'segment forrncorsp'ndin'o the curvature of the flloes o' the wheeh'andi't is provided with two partitions or abutments, a a, which have a radial position relatively with the wheel, and form chambers to receive theends of two of the fellocs, c, of the wheel, the ends of the felloes which'are fitted into said chambers being made in tenon form, as shown at d, so that the exterior of the. socket will be lush with the felloes, (see iig. 1,)

and the ends of the felloes abut against the partitions a a. The space between the partitions a a is open at the top or exterior of the socket, but closed at the inner side ta receive lips, e e, which are formed at the ends of the tire O. These lips, e e, project inward from the ends of the tire in an oblique direction, the space between them increasing in width from their outer to their inner ends, the front and rear sides -being parallel with each other. The inner end of each lip, e, has an arm, f, projecting from it in s. direction longitudinal with thesocket B, the arms` of the two lips projecting towards each other, but from opposite sides of the lips. D D represent keys which are fitted in the central compartment of the socket, one behind each lip e. The sides of these keys, opposite or adjoining the partitions a a, are parallel with them; but the opposite sides are inclined or oblique, and are parallel with the adjoining sides of the lips eve. Each key, D, has a screw-tang, f, projecting from it,

` and. these tangs extend through the inner side of the socket B, and have nuts, g, on them, as shown in iig. L.

Erepresents a key, the sides of which are of double inclined form, or of V-shape, and FF are two keys,whicl'rl correspond in form to the sides ofthe key E, azid are placed on'e at .each side of it, the lower part of each-key, F,' being provided with a lateral pin, h, to fit into a recess `in key E. (See iig. 2.) The lower outer surfaces of `he keys F are vertical, but the louter surfaces of the upper parts are inclined, flare outward, and correspond to.

theends of the tire C, which are bevelled to correspond to them. (See tig. 1.) The key E is provided with s.

' screw-tang, s', which extends through the inner sideof the socket B, and has a nut, j, upon it and the arms, `oi" the lips e e extend'und'erthe shoulders formed bythe junction of the tang t' with the lower end of key E. 'The tire C.when rst applied to the wheel, is heated and adjusted tightly on the wheel in the usual manner,

the key D F F, all being in the position as shownin iig. Vl, and the cuter surfaces of the keys E F Filush with the outer surfaeeor tread of the tire. In caseof the tire becoming loose by the shrinking of the wheel or other causes, the nutj of the tanga' is relaxed, and one of lthe keys F removed andthe keys D D secured down by turningl the nuts g, the inclined sides of the keys D acting against the rear inclined sides of the lips e, and drawing th ends of the'ti Goloso, one to thc remaining key F andmtheother tothc key E. The arms f of the lips e prevent the ends/of thetire being forced outward under the action ofthe keys D D. In case the removal of one-key, F, is not suicient, both keys may be withdrawn. Any number of keys, F, may be used, as

desired, one or more being placed at each side of key E, and in cases where the tire is but slightly loose it may,

be tightened suiciently by screwing down thekeys D D without withdrawing either key F, the ends of the tire extending under or within the outer ends of the keys F F. lThe arrangement is extremely simple and eidcient.

`and any-ou with `a proper wrenchvmay tighten the tire at any time, and Without any diiculty whatever,

Having thus described my invention, I claim as new, and desire to'secure by Letters Patent.- 1. The lips e at the ends of the tire C, in combination with the keys D D E, operated through the .medium of screws, and one or mprejremovable or adjustable keys F, all arranged substantially as and for the prpose set forth.
